Right Answer:
Data analysis is the process of inspecting, cleaning, and modeling data to discover useful information, draw conclusions, and support decision-making. It is important because it helps organizations make informed decisions, identify trends, improve efficiency, and solve problems based on data-driven insights.

Right Answer:
The different types of data analysis are:

1. Descriptive Analysis
2. Diagnostic Analysis
3. Predictive Analysis
4. Prescriptive Analysis
5. Exploratory Analysis

Right Answer:
To handle missing data in a dataset, you can use the following methods:

1. **Remove Rows/Columns**: Delete rows or columns with missing values if they are not significant.
2. **Imputation**: Fill in missing values using techniques like mean, median, mode, or more advanced methods like KNN or regression.
3. **Flagging**: Create a new column to indicate missing values for analysis.
4. **Predictive Modeling**: Use algorithms to predict and fill in missing values based on other data.
5. **Leave as Is**: In some cases, you may choose to leave missing values if they are meaningful for analysis.

Right Answer:
Descriptive statistics summarize and describe the main features of a dataset, using measures like mean, median, mode, and standard deviation. Inferential statistics use sample data to make predictions or inferences about a larger population, often employing techniques like hypothesis testing and confidence intervals.

Right Answer:
Classification analysis is a data analysis technique used to categorize data into predefined classes or groups. It works by using algorithms to learn from a training dataset, where the outcomes are known, and then applying this learned model to classify new, unseen data based on its features. Common algorithms include decision trees, logistic regression, and support vector machines.

Right Answer:
The main difference between rename and label is that rename changes the actual name of a variable or column in the dataset, while label provides a descriptive name or alias for the variable without altering its original name.

Right Answer:
To achieve this, you can create a calculated field or a mapping table that associates each country with its corresponding sales territory. Then, use this mapping to filter the report results based on the selected territory in the prompt. When "Asia" is selected, the report should filter to show only the countries that belong to the Asian territory.

Right Answer:
You can use the following code in SAS:

```sas
data _null_;
array vars{*} _all_;
do i = 1 to dim(vars);
put vname(vars{i});
end;
run;
```

This will print the names of the variables in the log window. To print them in the output window, you can use:

```sas
proc print data=_null_;
var _all_;
run;
```

However, since the dataset is null, you may need to create a dummy dataset to see the output in the output window.

Right Answer:
Merging in Framework Manager refers to combining multiple data sources or queries into a single model. Segments are used to break down large data sets into manageable parts for better performance and organization. Porting involves transferring a model or project from one environment to another, ensuring compatibility and functionality in the new setting.

Right Answer:
Estimating the costs of building a metro involves several factors, including land acquisition, construction materials, labor, equipment, and operational expenses. A rough estimate can range from $100 million to over $1 billion per mile, depending on the location, complexity, and design of the metro system.

Right Answer:
I would assess my surroundings for safety, check for injuries, find a safe location, signal for help, and gather supplies if possible.

Right Answer:
In my previous job, I had to manage multiple projects with tight deadlines. I created a prioritized to-do list, allocated specific time blocks for each task, and used project management tools to track progress. I communicated regularly with my team to delegate tasks and ensure everyone was aligned. As a result, we completed all projects on time, and the quality of work exceeded client expectations.

Right Answer:
